Why BEICHEN hydrofoils

The energy consumption of dewatering in the forming section is much lower than the steaming drying.

The ceramic hydrofoils dewatering element is installed in the forming section to drain water from wet web and offer support and protection to the forming fabric. After long time of constant operation, the hydrofoils will be worn or damaged when attacked by the aggressive chemicals, abrasives or debris, the surface will be uneven. The uneven ceramic surface will cause paper defects and destroy the wet web. Following problems will increase running cost to the paper making machine, like spare parts replacement, machine pause and daily maintenance.

Ceramic dewatering hydrofoils supplied by Beichen are with higher wear and abrasion resistance performance, and smoother surface. This can guarantee the constant running of the paper making machine. Benefits will be gained by installing Beichen hydrofoils.

Product Introduction

What is hydrofoil

The function of hydrofoils ("foils" for short) is to aid in removal of water from a wet web in the early stages of dewatering. On a Fourdrinier paper machine the foils are placed under the forming fabric. Their shape is designed to create suction as the foil and wet web pass over the surface. Hydrofoils also create a brief pressure pulse as the fabric passes over the leading edge. The alternating pressure and vacuum of a series of hydrofoils tends to move fibers around in the wet web, slightly improving the drainage and uniformity of the resulting paper. Also, the pulsation tends to change the drainage mechanism from pure filtration to a combination of filtration and thickening. The washing action of hydrofoils tends to remove fiber fines and fillers from the wire side(s) of a paper sheet. Another function of the hydrofoil is to doctor water from the under-side of the forming fabric.

Why installing hydrofoils

Paper formed by the forming boards contains massive water and fiber fines. The surface and thickness maybe uneven. Ceramic hydrofoils can help to remove the water in the leading edge and under-side of the forming fabric. Hydrofoils can be ground with angles for a more effective drainage performance. Fiber fines can be collected in the box and transferred to head box for reusing.

Main Function

The main key function of ceramic dewatering hydrofoil is to remove water from a wet web in the early stage of dewatering. It can also remove fiber fines for reusing.

How it works

The foils under the forming fabric is designed to create suction as the foil and wet web pass over the surface. Hydrofoils can create a brief pressure pulse as the fabric passes over the leading edge. The alternating pressure and vacuum of a series of hydrofoils tends to move fibers around in the wet web, slightly improving the drainage and uniformity of the resulting paper. Also, the pulsation tends to change the drainage mechanism from pure filtration to a combination of filtration and thickening. The washing action of hydrofoils tends to remove fiber fines and fillers from the wire side(s) of a paper sheet. Another function of the hydrofoil is to doctor water from the under-side of the forming fabric.

Insights of the design

The hydrofoils can be 3 striped, 5 striped, and 7 striped, the amount is determined by the comprehensive demands. Ceramic dewatering blades of hydrofoils are stitched on the RFP T-base and fixed on the corrosion resistant steel box.

Materials

Material for the water drainage box is corrosion-resistant steel.

Blade strips are in high wear resistant Alumina ceramic.

Hard strength FRP as the base for ceramic stitching.
